Commands

Every plugin must implement these subcommands.

Required Commands

`info`

Returns metadata and declares which optional capabilities your plugin supports.

entire-agent-myagent info

{
  "protocol_version": 1,
  "name": "myagent",
  "type": "MyAgent",
  "description": "MyAgent - AI-powered code editor",
  "is_preview": true,
  "protected_dirs": [".myagent"],
  "hook_names": ["session-start", "session-end", "stop"],
  "capabilities": {
    "hooks": true,
    "transcript_analyzer": true,
    "transcript_preparer": false,
    "token_calculator": false,
    "text_generator": false,
    "hook_response_writer": false,
    "subagent_aware_extractor": false
  }
}

Field	Description
`protocol_version`	Must match the CLI’s expected version (currently `1`)
`name`	Registry name (must match the `<name>` in the binary name)
`type`	Display name / type identifier
`description`	Human-readable description
`is_preview`	Whether the agent is in preview
`protected_dirs`	Directories the CLI should not modify (excluded from checkpoints and diffs)
`hook_names`	Agent lifecycle hooks this plugin handles
`capabilities`	Object declaring which optional capabilities are supported

`detect`

Returns whether the agent is available in the current environment. Return {"present": false} if the agent’s dependencies are not met — the CLI will skip enabling the agent.

entire-agent-myagent detect

{"present": true}

`get-session-id`

Extracts a session ID from a hook input event. stdin: HookInput JSON

{"session_id": "abc123"}

`get-session-dir --repo-path <path>`

Returns where agent sessions are stored.

{"session_dir": "/path/to/sessions"}

`resolve-session-file --session-dir <dir> --session-id <id>`

Resolves the session file path from a session directory and ID.

{"session_file": "/path/to/session/file.jsonl"}

`read-session`

Reads session data from a hook input event. stdin: HookInput JSON stdout: AgentSession JSON

`write-session`

Persists session data to disk. The plugin is responsible for choosing the storage location and format. stdin: AgentSession JSON Exit 0 on success.

`read-transcript --session-ref <path>`

Reads a transcript file and returns its raw bytes on stdout.

`chunk-transcript --max-size <n>`

Splits a transcript (raw bytes on stdin) into chunks.

{"chunks": ["<base64-encoded-chunk>", "..."]}

`reassemble-transcript`

Reassembles chunks back into a transcript. Called during entire checkpoint rewind to reconstruct transcript data from stored chunks. stdin:

{"chunks": ["<base64-encoded-chunk>", "..."]}

stdout: Raw transcript bytes.

`format-resume-command --session-id <id>`

Returns the command a user would run to resume a session.

{"command": "myagent --resume abc123"}

Optional Capabilities

Set capabilities to true in your info response to enable these. The CLI will never call subcommands for capabilities you don’t declare.

`hooks`

Manage agent lifecycle hooks for Entire integration.

Subcommand	Description
`parse-hook --hook <name>`	Parse a raw hook payload (stdin) into an Event. Return `null` if not relevant.
`install-hooks [--local-dev] [--force]`	Install hooks. `--local-dev` installs hooks pointing to a local development build. `--force` overwrites existing hook files. Returns `{"hooks_installed": 3}`.
`uninstall-hooks`	Remove installed hooks. Exit `0` on success.
`are-hooks-installed`	Check hook status. Returns `{"installed": true}`.

`transcript_analyzer`

Extract data from agent transcripts.

Subcommand	Description
`get-transcript-position --path <path>`	Returns `{"position": 12345}` (byte offset).
`extract-modified-files --path <path> --offset <n>`	Returns `{"files": [...], "current_position": 12345}`.
`extract-prompts --session-ref <path> --offset <n>`	Returns `{"prompts": ["prompt text", ...]}`.
`extract-summary --session-ref <path>`	Returns `{"summary": "...", "has_summary": true}`.

`transcript_preparer`

Subcommand	Description
`prepare-transcript --session-ref <path>`	Pre-process a transcript file. Exit `0` on success.

`token_calculator`

Subcommand	Description
`calculate-tokens --offset <n>`	Calculate token usage from transcript bytes (stdin). `--offset` is the byte offset into the transcript to start counting from.

Output:

{
  "input_tokens": 1500,
  "output_tokens": 500,
  "cache_creation_tokens": 0,
  "cache_read_tokens": 200,
  "api_call_count": 3
}

Only input_tokens and output_tokens are required. Other fields default to 0.

`text_generator`

Subcommand	Description
`generate-text --model <model>`	Generate text from a prompt (stdin). Returns `{"text": "..."}`.

`hook_response_writer`

Subcommand	Description
`write-hook-response --message <msg>`	Write a message in the agent’s native hook format (stdout).

`subagent_aware_extractor`

For agents that spawn subagents.

Subcommand	Description
`extract-all-modified-files --offset <n> --subagents-dir <dir>`	Extract modified files from main + subagent transcripts (stdin: main transcript). Returns `{"files": [...]}`.
`calculate-total-tokens --offset <n> --subagents-dir <dir>`	Calculate total tokens across main + subagent transcripts (stdin: main transcript). Same format as `calculate-tokens`, with optional `subagent_tokens` nested object.
